Mobile devices & DJ apps

Can an iPod be used?

What are the required specifications of mobile devices for using rekordbox (CPU specifications, OS versions, etc.)?

I connected a mobile device to this unit via a wireless LAN access point, but the mobile device switched to a different access point by itself.

rekordbox (Android) freezes when the Android smartphone/tablet is connected to the CDJ-2000NXS2 by Wi-Fi (wireless).

When an Android smartphone and the CDJ-2000NXS2 are connected by USB cable, the smartphone is not recognized by the CDJ-2000NXS2.

Can mobile devices (smartphones and tablets) be connected directly by wireless LAN?

When connecting and using the CDJ-2000NXS2 with a smart phone/tablet, is recharging possible?
